TRAVELING SPRINKLER.

Specification of Letters Patent.

Patented Mar. 28, 1916.

Application filed October 31, 1914. Serial No. 869,511.

To aZ7 whom it may concern:

Be it known that I, MALCOLM SALMOND, a citizen of'the United States, and a resident of the city of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Traveling Sprinklers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention has relation to the class of sprinkling devices known as traveling sprinklers in which the sprinkler for distributing a spray of water is moved over the ground so that the water is distributed toan extended area. In sprinklers of this class, the art has not yet brought forth a really practical device because of the difliculty of providing water to the sprinkler as it moves along.

It is the object of my invention to provide a light, durable traveling sprinkler with effective motor power, without water waste, and to provide a gneans for mounting the 'hose on the traveling frame. This'I accomplish by that certain construction and arrangement of parts to be hereinafter specifically pointed out and claimed.

In the drawings, Figure 1 is a top plan view of my device. Fig. 2 is a longitudinal vertical section thereof on the line 2, 2, of Fig. 3. Fig. 3 is a vertical section through the hose reel and the water pipes showing the revoluble pipe in elevation. Fig. 4 is a detail of the pawl-internal gear driving mechanism. Fig. 5 is a side elevation of the water valve at the hydrant.

The sprinkler has a carriage with a frame 1 and wheels 2, 2, mounted. fixedly on axles 3, 3. A water motor 4, with piston rod 5 is employed to drive the carriage, and the exhaust pipe 6 of the motor is connected to any desired sprinkling nozzle 7 mounted on the front of the frame. As the carriage is to be driven very slowly, there is not much water pressure expended in operating the motor, and with any ordinary head of water, there will be ample pressure at the nozzle to send a spray over considerable surface.

A vertical pin 9 is revolubly mounted in the frame and rigidly mounted thereon is a large internal gear 9 and a pinion 9 on its upper end. The piston rod 5 of the motor is pivotally connected at 5 to the pis ton and at its outer end is pivoted in a yoke 11,-- mounted so as to swing on the pin 9 (Fig. 4). On this yoke is a pivot pawl 12, with a beveled rear face 13, so as to be adapted when pulled toward the motor to engage the internal gear teeth, but when pushed back to slip over them, by a bending at the joint between the yoke and pawl.

A vertical shaft 10 is provided, having a gear 10 in mesh with the pinion 9 and having a beveled gear 14 in mesh with a like gear 15 on the front axle. It is then obvious that the motor at every back stroke turns the gear train to revolve the front wheels of the carriage.

Toward the rear of the carriage, behind the motor, is located the hose reel having reel arms 15, on hubs 16, 17, and cross arms 18 on which the hose 19 is mounted. Journals 15 are mounted on the two side frame pieces, and the hubs of the reel have sleeve portions 16 17 cast with them of a size to fit said journals. In mounting the reel, the journal boxes are set over the sleeves before they are bolted to the frame.

A pipe 20 is provided, adapted to be mounted in the sleeve 16 and having a fixed connection 23 with the motor intake, by which it is held rigid, and a revoluble pipe 21 is provided, journaled at one end in the sleeve 17 so as to revolve, and provided with a revoluble water-tight coupling 22 to the pipe 20. This coupling can be of any desired kind, provided that it is watertight and will permit flow of water from the pipe 21 into the pipe 20. The pipes thus run axially through the reel with one of them free to revolve with it, and the hose 19 is wound around the reel, with its coupling end 24 secured to the coupling piece 21 in this revoluble pipe section 21.

It can thus be seen that, when the hose is wound on the reel, as described, with its free end secured to a hydrant, the water will flowthrough it to the pipes 21, 20, through these to the motor, thereby driving the carriage, and from the motor to the sprinkling nozzle. As the carriage is moved slowly f0r w ard,the reel will turn allowing the hose to unwind, without disturbing its connection to the pipe 21 which revolves with the reel.

The carriage of such a device may be of light and inexpensive material; the water motor not being called upon for heavy duty may be of the most inexpensive kind, and the gears and most of the metallic parts can be of cast iron as there is but little strain on them owing to the slow movement of the carriage. The hose is carried on the carriage, "-Wound upon the reel so as not to become tangled or drag on the ground, and all the Water passing through the machine is used in sprinkling.

I For turning off the Water When the reel has unwound, or at any desired point, a cord may be provided, wound on a spool 26 on the carriage and secured to the spool 26 so as to extend free the distance desired. Its other end is secured to the lever 27, at the hydrant, which is connected to a shut-off valve in the pipe. The lever is preferably, under spring pressure, through a spring 28, secured parallel to the lever at its midway point so that the lever is adapted to be pulled part Way closed against the spring pressure by the slow movement of the carriage, and when it has passed its middle point to be pulled over at once to closed position by the spring.

The method adapted to close the Water is merely my preferred form, as any simple means Would be just as effective. It is not desired to be limited in the claims that follow to any specific feature of my device Where not claimed as such.'

The machine can be of any desired size and geared to any speed, but the light, slow moving structure is best adapted for garden and lawn sprinkling.

Having thus described my invention, What I claim as new and desire to secure by Letters Patent, is:

1. In a sprinkler device, a carriage, a hose mounted on the carriage, a Water motor on said carriage, connection to said motor from the hose, a sprinkler nozzle, connections from the motor exhaust to the nozzle, a source of supply of Water" and means for automatically turning off the same at any desired position of the sprinkler.

2. In a sprinkler device, a carriage, a reel revolubly mounted on the carriage, a revoluble pipe mounted on said carriage so as to lie along the aXial line of the reel, a Water driven motor mounted on said carriage to drive the carriage, connection from the revoluble pipe to said motor, a hose mounted on said reel and a-nozzle for said device connected to the Water motor exhaust, a source of supply of Water connected to the hose, and means on the carriage to shut oii the Water at the source.

3. In a sprinkler device, a carriage, a reel revolubly mounted on the carriage, a revoluble pipe mounted on said carriage so as to lie along theaxial line of the reel, a Water driven motor mounted on said carriage to drive the carriage, non-rotating connection from the revoluble pipe to said motor, a hose mounted on said reel, a sprinkler nozzle and connection from the motor exhaust to the nozzle, a source of supply of Water connected to the hose, and means on the carriage to shut off the Water at the source.
